Smart Fountains very interesting:

That is actually a great idea. Another idea would be to use such services e.g. in the museums.

I've noticed that in some museums you have to pay for the lighting for some minutes of some objects (pictures, sculptures or facade elements). You have to pay for this with coins, I think it would be much easier and more modern to pay for it with IOTA App. Just an another idea.
